I downloaded the newest version of xtools so I could follow along in a book about C++. The last time I did anything in the book was over 5 years ago, and my dad just set up the software I needed to do the examples in it. I made a blank C++ document, and it asked if I wanted to make a corresponding ".h" file, which I declined. Is this where the definitions for certain functions are stored? If so, is that the file I should refer to in my headers? The book says, for example, Borland C++ uses IOSTREAM.H for stream-related definitions, while Microsoft Visual C++ uses other headers in addition to that; how does it work in xcode? In addition to not knowing that, I'm not really sure how to test the code that I'm putting in. I get the general idea of the targets, but I don't know which to choose or how to set them up. If anyone could guide me through setting up xcode to let me work through this book that would be a great.
